Requirements from Session Initiation Protocol Session Border Control Deployments
RFC 5853, “Requirements from Session Initiation Protocol Session Border Control Deployments”, is an Informational document published in April 2010 by J. Hautakorpi, G. Camarillo, R. Penfield, A. Hawrylyshen, M. Bhatia. The canonical text is published by the RFC Editor.
Abstract
This document describes functions implemented in Session Initiation Protocol (SIP) intermediaries known as Session Border Controllers (SBCs). The goal of this document is to describe the commonly provided functions of SBCs. A special focus is given to those practices that are viewed to be in conflict with SIP architectural principles. This document also explores the underlying requirements of network operators that have led to the use of these functions and practices in order to identify protocol requirements and determine whether those requirements are satisfied by existing specifications or if additional standards work is required. This document is not an Internet Standards Track specification; it is published for informational purposes.
What “Informational” means
Published for the general information of the community. It does not define an IETF standard and carries no standards-track status.
